How to detect a current form change

Sutlieff

Hi,

I have  a form (using hiCreateLayoutForm)  invoked from layout A (GUI1) . I have a second form invoked from layout B (GUI2). 

GUI2 is currently the active form 

I would like to detect when the user has clicked back into GUI1.

Has anyone got an idea how to do this?

The closest I got was to use ?focusInCallback  when creating a string field ( hiCreatestringField).

When clicking in this string field I could jump to my procedure and then get the new form with hiGetCurrentForm().

I was looking for something that detected when I  clicked anywhere on a form.

  • Hi Colin,

    I don't believe this exists in an easy fashion. Why would you need it? There's a clunk workaround which would be to use hiRegTimer to regularly check whether hiGetCurrentForm() changes and call your own trigger when it changes, but I'm not sure I like using a polling approach to do this.

    Hi Andrew,

    thanks for the info.

    There is, in fact, another (different) form (only one instance) that gets populated with data from the active form. I didn't mention this in the original post.

    This is not a very elegant way, I admit, and in the future, I'll put put all the data into the one main GUI using tabs, not spread the data between 2 forms

    I guess that the QT framework can detect window changes but not SKILL.

    Hi Colin,

    Actually SKILL does have support for a trigger for detecting window changes (hiRegCurWindowTrigger), but this is for windows not the transient windows used in forms. Also, it's actually when the window becomes current which is not quite the same as receiving focus.

    As you say though, not all of the underlying capabilities of the Qt framework are exposed in SKILL.

    Regards,

    Andrew.
